Defining IPv6 Addresses
To assign an IPv6 address to an IPv6 Interface:
STEP 1 In Layer 2 mode, click Administration > Management Interface > IPv6
Addresses.
In Layer 3 mode, click IP Configuration > Management and IP Interface > IPv6
Addresses.
The IPv6 Address Page opens.
STEP 2 Select an interface, and click Go. The interface is displayed in the IPv6 Address
Table.
STEP 3 Click Add. The Add IPv6 Address Page opens.
STEP 4 Enter the values for the fields.
• IPv6 Interface—Displays the interface where the address is automatically
completed, based on the filter.
• IPv6 Address Type—Select Link Local or Global as the type of IPv6
address to add.
- Link Local—The IPv6 address uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
• IPv6 Address—The switch supports one IPv6 interface. In additional to the
default link local and multicast addresses, the device also automatically
adds global addresses to the interface based on the router advertisements
it receives. The device supports a maximum of 128 addresses at the
interface. Each address must be a valid IPv6 address that is specified in
hexadecimal format by using 16-bit values separated by colons.
NOTE You cannot configure any IPv6 addresses directly on a ISATAP tunnel
interface.
• Prefix Length—The length of the Global IPv6 prefix as a decimal value from
0-128 indicating the number of the high-order contiguous bits of the address
comprise the prefix (the network portion of the address).
